DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath tub apparatus provided with a stretcher transfer rail for bathing a disabled person or the like who is unable to walk with a stretcher.

[0002]

2. Description of the Related Art Some bathtub devices for bathing persons with physical disabilities such as the elderly and the physically handicapped (hereinafter sometimes referred to as patients) include those in which a patient is bathed on a stretcher. is there. In a bathtub apparatus provided with such a stretcher transfer rail, a stretcher transfer rail is basically provided in the bath. This stretcher transfer rail is
It can be displaced in the vertical direction relative to the bathtub, and can take a high position for transferring a stretcher and a low position for taking a bath (for example, Japanese Patent Laid-Open No. 3-149).
048).

When a patient is to take a bath, the patient is placed on a stretcher on a carrier and transferred to the bathtub, and then the transfer rail on the carrier provided on the carrier is moved to the stretcher on the bathtub at the high position. Aligned with transfer rail. Thereafter, the patient is transferred to the stretcher transfer rail on the bathtub side together with the stretcher. The stretcher transfer rail on the bathtub side on which the patient is placed is lowered relative to the bathtub to be in the low position, whereby the patient is bathed in the bath water. After the end of bathing, the patient is transferred from the bathtub to the transport vehicle together with the stretcher in a procedure reverse to the procedure described above.

[0004]

By the way, when the stretcher transfer rail on the transporting vehicle side and the stretcher transfer rail on the bathtub side are aligned with each other, the conventional one has a considerably large space between both the stretcher transfer rails. A gap was to be formed. That is, since the stretcher transfer rail on the bathtub side is displaced up and down relative to the bathtub, its length, that is, the position of the longitudinal end is on the bathtub inner wall surface so as not to interfere with the bathtub inner wall surface. Is short enough not to reach. On the other hand, since the transfer of the stretcher is performed over the upper edge of the bathtub, if the two stretcher transfer rails are aligned, at least a gap corresponding to the length corresponding to the upper edge of the bathtub. Was to be formed.

[0005] Because of the large gap, a large shock is likely to occur when transferring the stretcher. Also, in order to avoid such a large shock, the nurse must perform the transfer work while supporting the considerable weight of the stretcher on which the patient is riding when going over the large gap, which imposes a burden on the nurse. It will be extremely large.

In order to eliminate the large gap as described above,
It is also conceivable to set the stretcher transfer rail on the transport vehicle side to be sufficiently long, that is, a length that extends beyond the upper edge of the bathtub to near the inner wall surface of the bathtub. However, in this case, the stretcher transfer rail on the carrier side protrudes greatly from the carrier, and cannot be practically adopted.

[0007] The present invention has been made in view of the above circumstances, and its purpose is to align a stretcher transfer rail on a transport vehicle side with a stretcher transfer rail on a bathtub side. It is an object of the present invention to provide a bathtub apparatus provided with a stretcher transfer rail in which a large gap is not formed between the stretcher transfer rails.

[0008]

Means for Solving the Problems In order to achieve the above object, the present invention has the following configuration. That is, in the bathtub, a stretcher transfer rail is provided, and the stretcher transfer rail can be displaced up and down relative to the bathtub, and a high position and a bathing state for transferring the stretcher. In a bathtub apparatus provided with a stretcher transfer rail configured to be able to take a low position, the stretcher transfer rail extends substantially horizontally and does not interfere with the inner wall of the bathtub due to vertical displacement relative to the bathtub. A main body rail set to a length, and an extension rail attached to the end of the main body rail so as to be vertically swingable and having a roller rotatably provided at the end thereof.
The inner wall surface of the bathtub is inclined so as to face outward in the direction of extension of the main body rail as it goes upward, and the extension rail extends substantially horizontally in the extension direction of the main body rail and is higher than the inner wall surface of the bathtub. Further, an extended position extending to the outside of the bathtub and an inclined state swinging upward from a state of extending substantially horizontally, the roller is brought into contact with the inner wall surface of the bathtub while being in contact with the inner surface of the bathtub. It is configured so as to be able to take a storage position where relative vertical displacement is performed. Preferred embodiments of the present invention based on the above configuration are as described in Claims 2 and 3 in the claims.

[0009]

According to the first aspect of the present invention, at a high position where the stretcher is transferred, the stretcher transfer rail on the transport vehicle side and the main body rail among the stretcher transfer rails on the bathtub side are disposed. Since the extension rail located at the extension position is present in the large gap portion, the large gap which has existed conventionally is eliminated, and the transfer of the stretcher can be performed smoothly. After the transfer of the stretcher, by placing the extension rail in the storage position, there is no problem in lowering the stretcher transfer rail on the bathtub side for bathing without interfering with the inner wall surface of the bathtub. Will not be.

Further, the extension rail at the extended position at the high position can be automatically set to the storage position in accordance with the downward displacement of the stretcher transfer rail with respect to the bathtub, and the stretcher is moved from the storage position to the storage position. By displacing the transfer rail upward with respect to the bathtub, the extension rail can be automatically brought to the extended position. In addition, when the extension rail is moved up and down relative to the bathtub in an inclined state, it is preferable in terms of ensuring smooth movement with respect to the bathtub inner wall surface and preventing damage to the bathtub inner wall surface. Furthermore, based on the inclination of the inner wall surface of the bathtub, the extension rail can be brought closer to the extension position in the storage position, and the stretcher transfer rail on the bathtub side can be raised to a higher position. When raised, the reliability that the extension rail automatically assumes the extension position can be further increased.

According to the second aspect of the present invention, in a case where the stretcher transfer rail on the side of the carrier is located considerably inward from the outer surface of the carrier, The gap between the stretcher transfer rail on the transport vehicle side and the stretcher transfer rail on the bathtub side can be reduced.

[0012] With the configuration as described in claim 3, the extension rail, which is in the extension position and receives a large weight during transfer of the stretcher, can be firmly supported by the bathtub itself.

[0013] With the configuration as described in claim 4, the transfer of the stretcher can be selectively performed from any direction of the end portions of the rail for transferring the stretcher.

According to the structure described in claim 5, in order to prevent damage to the upper edge portion of the bathtub and the inner wall surface of the bathtub with which the extension rail comes into contact, and to smoothly slide the extension rail against the inner wall surface of the bathtub. It is also preferable for securing

[0015]

In FIGS. 1 and 3, reference numeral 21 denotes a carrier. The carrier 21 has a water receiver 22 having a large area on its upper surface.
A stretcher transfer rail 23 on the carrier side is provided above the water receiver 22. This stretcher transfer rail 23 is also provided in a pair, and the interval is
The interval is set to be the same as the interval between the pair of stretcher transfer rails 12 on the side of the bathtub 1.

In FIG. 1 to FIG. 3, reference numeral 31 denotes a stretcher, which has wheels 32 on its lower surface which can run on the stretcher transfer rail 23 (12). A plurality of the wheels 32 are provided at small intervals in the longitudinal direction of the stretcher transfer rail 23 (12), and have a flange portion 32a so as not to come off as shown in FIG.

In the above configuration, the patient A is placed on the stretcher 31 on the transport vehicle 21 and transferred to the side of the bathtub 1. By positioning rollers 24 as positioning protrusions provided on the sides of the transport vehicle 21 in the engagement recesses 4a of the positioning members 4 provided on the side surfaces of the bathtub 1, the positioning of the transport vehicle 21 with respect to the bathtub 1 is achieved. Done.

Before or after the positioning of the transport vehicle 21 with respect to the bathtub 1, the elevator 12 moves the stretcher transfer rail 12 on the bathtub 1 side to the high position shown in FIG. It is a horizontal extension position. In this state, the stretcher transfer rail 23 on the transport vehicle 21 side and the stretcher transfer rail 12 on the bathtub 1 side are in an aligned state positioned on the same straight line. In this aligned state, a large gap is formed between the stretcher transfer rail 23 on the side of the transport vehicle 21 and the main body rail 13 of the bathtub 1, and the extension rail 14 is located in this large gap. (See FIG. 3). That is, the stretcher transfer rail 23 and the main body rail 13 are connected via the extension rail 14 with almost no gap.

From the state shown in FIG. 3 in which the stretcher transfer rail 23 and the main body rail 13 are connected via the extension rail 14,
The stretcher 31 on the transport vehicle 21 is moved toward the bathtub 1, and the stretcher 31 is transferred onto the main rail 13 of the bathtub 1. At this time, the stretcher 3
1 is smoothly moved from the stretcher transfer rail 23 on the carrier 21 to the main body rail 13. Also,
The load applied to the extension rail 14 from the stretcher 31 is
Is firmly supported by the upper edge portion 1a.

The stretcher transfer rail 1 is moved by the cylinder device 10 from the state where the stretcher 31 is transferred on the main rail 13.
Lower 2 At the time of this descent, the extension rail 14
Upon receiving an external force from the inner wall surface 1b of the bathtub 1, the bathtub 1 is automatically displaced to the storage position which has swung upward. Then, the patient A on the stretcher transfer rail 12, that is, the stretcher 31, is lowered to a predetermined low position, and the patient A is bathed.

When the bathing of the patient A is completed, the stretcher transfer rail 12 (main body rail 13) on the side of the bathtub 1 and the stretcher transfer rail 23 on the carrier 21 are reversed in a procedure reverse to the above-described procedure up to bathing. , The stretcher 31, that is, the patient A is transferred. That is, the stretcher transfer rail 12 is raised by the cylinder device 10 from the low position that is the bathing position,
It returns to the high position shown in FIG. When the stretcher transfer rail 12 is raised toward this high position, the extension rail 14
Is raised while sliding on the inner wall surface 1a of the bathtub 1. Then, when reaching the predetermined height position shown in FIG. 3, the extension rail 14 is automatically set to a substantially horizontal extension position by its own weight. Thereafter, the stretcher 31 is transferred from the main rail 13 on the bathtub 1 side to the stretcher transfer rail 23 on the carrier 21 via the extension rail 14.

FIGS. 5 to 7 show details of a connecting portion between the main body rail 13 and the extension rail 14, and a preferable configuration of the extension rail 14. FIG. First, a pair of mounting legs 1 is formed at an end of the main body rail 13 so as to form a mounting groove 41.
3a are formed. The mounting groove 41 has a shape that opens on the distal end surface and the upper and lower surfaces of the main body rail 13. On the other hand, at the end of the extension rail 14 on the side of the main body rail 13, a narrow mounting protrusion 14 a extending into the mounting groove 41 is provided.
Is formed, and the pin 15 serving as the center of rotation of the extension rail 14 passes through the mounting protrusion 14a and the pair of legs 13a. In the embodiment, the pin 15 is constituted by a bolt and is prevented from coming off by a nut 16.

In the extended position shown in FIG.
And the upper surface of the extension rail 14 are substantially flush, that is, there is no step on the traveling road surface of the wheels 32 of the stretcher 31. In addition, the main body rail 13 and the extension rail 14 are set so that the inner side surface and the outer side surface are also flush.

An extension rail 1 is provided on the lower surface of the extension rail 14.
A block member 42 made of a synthetic resin is fixed by a screw 43 over a predetermined length from the front end of 4. The block member 42 is made of a material having relatively high rigidity such as Teflon or nylon and having a small frictional resistance.

When the block member 42 is in the extended position shown in FIG. 3, it is in contact with the upper edge 1a of the bathtub 1 so as not to damage the upper edge 1a. Also,
When the extension rail 14 is in the storage position, the block member 41 is in contact with the inner wall surface of the bathtub 1. That is, the extension rail 1 is
4 prevents damage to the inner wall surface 1b of the bathtub 1 and reduces sliding resistance. As described above, the block member 42 has both a function as a buffer member for preventing damage to the member on the side contacting the extension rail 14 and a function as a sliding resistance reducing member.

The main rail 13 is made of a metal having excellent corrosion resistance such as stainless steel.
The portions other than the block member 42 in 4 are also formed of a metal having excellent corrosion resistance such as stainless steel.

Here, of the tip of the extension rail 14,
As shown in FIG. 5, a roller 44 is rotatably provided on a portion which is moved up and down while being in contact with the inner wall surface 1b of the bathtub as shown in FIG. The inner wall surface 1b can be prevented from being damaged. In this case, it is preferable that at least the outer peripheral surface (the contact surface with the bathtub inner wall surface 1b) of the roller 44 is formed of an elastic member such as rubber or a synthetic resin in order to further prevent damage to the bathtub inner wall surface 1b. The roller 44 can be formed entirely of an elastic member or a synthetic resin. Of course, such a roller 44 can be used as the block member 4 as shown in FIG.
2 can be used together with the block member 42
(No block member).

Here, it is conceivable to provide an extension rail for the stretcher transfer rail 23 on the side of the transport vehicle 21. However, in view of the fact that the number of carriers 21 is much larger than the number of bathtubs 1, it can be easily understood that it is much more advantageous to provide an extension rail on the stretcher transfer rail on the bathtub 1 side. You.

Although the embodiment has been described above, the present invention is not limited to this and includes, for example, the following case.

(1) The stretcher transfer rail 12 only needs to be able to be displaced in the vertical direction relative to the bathtub 1. For this purpose, the vertical position of the stretcher transfer rail 12 is fixed, and only the bathtub 1 is moved up and down. It may be displaced in the direction.
Further, as shown in the above-mentioned JP-A-3-149048, both the stretcher transfer rail 12 and the bathtub 1 can be displaced in the vertical direction, and when the stretcher transfer rail 12 is displaced downward, the bathtub 1 moves upward. It may be displaced (so that the bathtub 1 is displaced downward when the stretcher transfer rail 12 is displaced upward). Of course, the drive source for raising and lowering can be appropriately selected such as an electric motor.

(2) The extension rail 14 (54) may be provided only at one end of the main body rail 13 (53). However, as shown in the embodiment, providing the extension rails at each end of the main body rail is advantageous in that the carrier 21 can be approached from both the left and right sides of the bathtub 1. .

(3) The switching of the extension rail between the extension position and the storage position may be performed by using a drive source such as a hydraulic cylinder separately. In this case, the driving source is
What is necessary is just to provide in a main-body rail. In addition, the drive source is automatically controlled, and when the stretcher transfer rail is at the high position, the extension position is automatically set to the extended position. The driving may be controlled so as to be performed.

(4) In the embodiment shown in FIGS.
In consideration of the swing resistance of the extension rail 14 with respect to the main body rail 13, a spring is provided to urge the extension rail 14 toward the extension position so that the extension rail 14 is reliably extended at the high position. Is also good. In this case, the spring urges the extension rail 14 from the storage position shown in FIG. 2 so that the extension rail 14 becomes substantially horizontal. For example, a spiral spring surrounding the pin 15 can be used. (5) A sliding resistance reducing member such as a synthetic resin (inner wall surface 1b) or a cushioning member such as rubber may be provided in a portion of the bathtub 1 where the extension rail 14 is in contact (upper). Edge 1a). (6) A stopper may be provided on the main rail 13 to restrict the extension rail 14 from swinging further downward from the extended position at which the extension rail 14 is substantially horizontal.
